About 450 nonnative, plant-eating insect species live in North American forests. Most of these critters are harmless, but a handful wreak havoc on their new environment, attacking trees and each year causing more than $70 billion in damage. | Continue reading
During Earth's last glacial period, temperatures on the planet periodically spiked dramatically and rapidly. Data in layers of ice of Greenland and Antarctica show that these warming events—called Dansgaard-Oeschger and Antarctic Isotope Maximum events—occurred at least 25 times. … | Continue reading
Predicting and controlling disease outbreaks would be easier and more reliable with the wider application of mathematical modelling, according to a new study. | Continue reading
According to Noël Coward, mad dogs and Englishmen are the only creatures that go out in the midday sun, but Harald Wolf from the University of Ulm, Germany, would add another animal: Saharan silver ants (Cataglyphis bombycina).

An international research team led by scientists from McMaster University has unearthed new evidence in Greece proving that the island of Naxos was inhabited by Neanderthals and earlier humans at least 200,000 years ago, tens of thousands of years earlier than previously believed … | Continue reading
When cells in our bodies need to move—to attack an infection or heal a wound, for example—cellular proteins send and receive a cascade of signals that directs the cells to the right place at the right time. It's a process cancer cells can hijack to spread to new tissues and organ … | Continue reading
Ecologists and biologists compared data of about 1,500 agricultural fields around the world, including corn fields in the American plains, oilseed rape fields in southern Sweden, coffee plantations in India, mango plantations in South Africa and cereal crops in the Alps. They ana … | Continue reading
Agricultural Research Service (ARS) scientists, in cooperation with Pacific Biosciences and Penn State University, have published the first genome of the invasive Spotted Lanternfly (SLF) in the journal Gigascience and they did it from a single caught-in-the-wild specimen. | Continue reading
Tropical Depression Fifteen or TD15, developed off the west coast of Africa on Oct. 14 by 5 p.m. EDT. The depression never strengthened into a tropical storm before it reached the end of its life. NASA's Terra satellite provided an image of TD15 after stretched out and ceased be … | Continue reading
In what sounds like a scene from a science fiction movie, researchers in 2005 stitched together old and young mice so they shared a circulatory system. Youthful blood seemingly rejuvenated many tissues of the elderly rodents, boosting their cognitive and physical performance. Now … | Continue reading
NASA's Precipitation Measurement Missions (PMM) have collected rain and snowfall from space for nearly 20 years, and for the first time in 2019, scientists can access PMM's entire record as one data set. | Continue reading
Squids, octopuses, cuttlefish, amphibians, and chameleon lizards are among the animals that can change the color of their skin in a blink of an eye. They have photoreceptors in their skin that operate independently of their brain. The photoreceptors are part of a family of protei … | Continue reading

SpaceX wants spectrum access for nearly four times as many satellites as originally planned for its high-speed internet constellation, the company and a UN agency confirmed Wednesday. | Continue reading
As global temperatures continue to rise, the thawing of permafrost in Arctic areas is being accelerated and mercury that has been trapped in the frozen ground is now being released in various forms into surrounding waterways, soil and air. According to researchers at the Universi … | Continue reading
Although LEDs are increasingly used in low-energy lighting and displays, consumers sometimes find their light harsh or unpleasant. Findings from a new study point to the need to take age-related perception differences into account when designing white LED lighting that is more pl … | Continue reading
The birthplaces of planets are disks made out of gas and dust. Astronomers study these so-called protoplanetary disks to understand the processes of planet formation. Beautiful images of disks made with the Atacama Large Millimeter/submillimeter Array (ALMA) how distinct gaps and … | Continue reading
When clouds loft tropical air masses higher in the atmosphere, that air can carry up gases that form into tiny particles, starting a process that may end up brightening lower-level clouds, according to a CIRES-led study published today in Nature. Clouds alter Earth's radiative ba … | Continue reading
Germany said Wednesday it had called a special meeting of international partners this week to pressure Royal Dutch Shell to remove old rigs containing crude oil in the North Sea. | Continue reading
The undying popularity of sport-utility vehicles has made them the second-biggest contributor to the growth of global CO2 emissions in recent years, just behind the power sector, the head of the International Energy Agency said Wednesday. | Continue reading
Despite humanity's best efforts to eradicate malaria, the disease struck more than 200 million people in 2017, according to the World Health Organization. Worse yet, the parasite that causes malaria is developing resistance to many antimalarial drugs, including the mainstay, chlo … | Continue reading
